Naproxen is an Aspirin-like analgesic.
Naproxen is often used to treat conditions such as arthritis, menstrual cramps, headaches, and back pain. It works by inhibiting the production of prostaglandins, which are substances that cause pain, inflammation, and fever in the body.
Naproxen is available over-the-counter in lower doses, while higher doses require a prescription. It can be taken orally as a tablet or capsule, or used topically as a gel or cream.
